Companies and individuals: 3 months to update official exchange rates or deviation risks

The Bank of Spain publishes the euro exchange rates as of March 9, 2026, under Article 36 of Law 46/1998. These rates are official and must be used in financial transactions, affecting all parties involved in currency conversions, especially in international trade, financial services, and cross-border payments.

In 3 key points

  1. Official exchange rates are updated daily by the ECB (Article 36 of Law 46/1998) (art. 36 Ley 46/1998)
  2. 1 euro = 1.1555 US dollars (official rate as of 9 March 2026) (cambio 1 euro = 1,1555 dólares USA)
  3. Exchange rates are considered official from the day they are published in the BOE (art. 36 Ley 46/1998)

How it affects those involved

Traders and international businesses must update their foreign currency pricing and cost calculations to avoid errors in invoices or payments. Individuals making foreign purchases or travel can now use the new official exchange rates. Banks and financial advisers must incorporate the updated rates into their calculation systems and communicate them to their clients. Using outdated exchange rates may result in losses or discrepancies in transactions.
